RADIATOR .HIEA'ILER.v

Application type, for the purpose of preventing the freezing of the water in the cooling system. Another lmportant obyect of the inventlon 1s to provide a radlator heater of the above mentioned character, which is adapted toutilize the hot exhaust gases from an internal combustion engine for the purpose of,

heating the radiator which contains the water in the cooling system of an internal combustion engine whereby the water within the cooling system is prevented from freezing.

A still further object of the invention is to provide a radiator heater of the above H1611? tioned character, which may be easily and readily placed in position upon an automo.

bile when it is desired to use the same without the necessity of having to disturb or otherwise effect the various parts of the in: ternal combustion engine.

I Another important object is to provide a radiator heater which utilizesthe prodnets of combustion from the internal com bustion engine and which passes through the exhaust manifold for the purpose of heating the radiator and which will .discharge the hot exhaust gases afterthe same have been used for heating the radiator in a suitable manner.

Other objects and advantages of "this in vention will become apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals designate like parts throughout the same Figure 1 is a side elevation of an internal combustion engine and the radiator associated therewith, with my heater shown partly in section and mounted on the radiatOI. v

vFigure 2 is a front elevation of a radiator with my heater mounted thereon. I

In the drawings wherein for the purpose of lllustratlon is shown the preferred embodiment of my invention, the numerall' designates, an internal combustion engine which is of the well known'type and includes the usual exhaust manifold 2. Associated with the. internal combustion engine 1 in the well known manner is the radiator 3. The construction thus far described and the parts mentioned, are inaccordance with the present construction and arrangement of parts. are to be found on the automobiles nowin use. a

The heater which comprises my invention and which is adapted to be connected with the various parts of the combustion engme above described, comprises a hollow casing or frame designated by the numeral 4 in the drawings and is substantially rectangular in design. The ends of the hollow frame 4 are connected together by means of the hollow tubes 5. These hollow tubes 5 extend across the frame from one end to the opposite end' and are arranged in parallel spaced relation as more clearly shown in Fig; 2 of the drawings. The end member 6 is provided with an extension 7 which is in the form of a tubular member and the opposite end member 8 is provided with a.

downwardly extending tubular portion designated by the numeral 9. The'purpose of these extensions will be hereinafter more fully described. The heater is adapted to be supported upon the radiator 8 at the lower portion thereof and is preferably adapt- 'ed to extend across the radiator as more clearly shown in Fig. 2 of the drawings.

The means for supporting and mounting the heater upon the radiator may be of any well known character and it is not thought necessary to go in detail as to the manner in which the heater is supported for the reason that it has no importance to the invention of my heater.

\Vhen the heater is supported upon the radiator, the rearwardly extending portion 7 is connected to the forward end of the exhaust manifold by means of the pipe 10 whereby-the exhaust gases which ordinarily pass through the exhaust manifold 2 will be caused to pass through the pipe 10 and through the heater. For the purposes of obtaining this result, I provide a cutoff valve 11 adjacent the rear portion of the exhaust manifold 2 and also a cutoff valve 12 is situated in the exhaust manifold adjacent the connection to the connecting pipe. The purpose of providing these cutoff valves 1.1 and 12 respectively is to enable the exhaust gases in the manifold 2 to be utilized for the purpose of heating the water passing through the radiator 3 in the water cooling system of the motor vehicle. This is especially necessary during cold Weather and the exhaust gases passing through the exhaust manifold 2 and the pipe 10 will pass through the pipe 6 and through the horizontally extending pipes 5 whereby the water within the radiator 2 will be caused to become heated and will prevent the freezing of the water in the radiator. It is to be further understood that the exhaust gases after passing through the heater will pass out through the end member 8 and finally be discharged through the extension 9 at the lower end of the member 8.

The heater may be mounted either on the outside of the radiator 3 or on the inside as is seen it but will perform the same result so long as the radiator extends across the radiator whereby the exhaust gases will come in contact therewith and heat the water passing through the radiator.

When it is desired to remove the heater from the radiator and this is necessary dur ing the warm weather, the pipe 10 is disconnected from the forward end of the exhaust manifold 2 and the cutoff valve 12 is actuated to close the opening and the cutoff valve 11 in the rear end of the exhaust manifold 2 is open so as to permit the exhaust gases to pass through the exhaust manifold in the usual manner. The heater is then disconnected from its supported position upon the radiator and thereby renders the motor vehicle operable without the necessity of having to remove the radiator or the various parts with which the heater is associated.

It will be seen from the foregoing clescription that a heater has been provided which is especially adapted for use upon a radiator in cold weather whereby the exhaust gases are utilized for the purposes of heating the water passing through the radiator and the cooling system and will thereby add to the etficiency of the operation of the motor vehicle and will also prevent the bursting of the radiator which sometimes occurs due to the freezing condition of the water contained therein.

From the foregoing descr ption of the construction of my improved apparatus, it will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the function's set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to, without departing from the spirit or sacrificing any of the principles of the invention.

What I claim as new and desire to secure by Letters Patent is The combination with an internal combustion engine including an exhaust manifold and a radiator associated therewith; of a heater extending across the lower portion of the radiator and on the outside thereof, said heater comprislng a frame formed of a smgle tube of metal designed square in cross-' section and bent to form upper and lower horizontal tubes and vertical parallel end tubes, a plurality of spaced apart intermediate tubes connected with the end tubes to communicate with the latter, said intermediate tubes being also square in cross-section, a tubular connection between the exhaust manifold and the one end tube of the frame to convey exhaust gases to the latter, an integral extension formed on the opposite end tube of the frame directed downwardly and rearwardly of the radiator to form a discharge pipe, and cut off valves arranged in said exhaust manifold to supply the exhaust gases to the heater, as and for the purposes described.

In testimony whereof I affix my signature.
